Magnetic levitation globe using current magnetic effect makes the globe float in midair.At the top of Globe there is a magnet,a coil of wire inside the top of circular plastic box,metal coil by current will become electromagnet.The suction between electromagnet and the globe top magnet can be offset by the gravity of the globe, so the globe can float in midair.Touch globe gently to deviate from the equilibrium position,the globe will return to the balance position and will not drop without hand.This is the use of negative feedback mechanism.

Magnetic levitation globe is a product which is helpful for kids to learn geography knowledge and cognitive work; Teach through lively activities and improve the children's interest of electric, magnetic, conversion of energy and more scientific knowledges.
